Problem burning VCDs on NeroExpress 3

Everytime I try to burn a VCD on Nero Express or Ulead Picture Show with menu (with music), I always get an error meesage and it ends of the process. In the middle of the burning progress (it usually crashes when it starts writing the video files)

But if I use the simple Video CD program on Nero 6 (the one where you cant include music on the menu), it burns completely without any problems. Why is that? How can I get Nero Express and Ulead to work?

But however, I do have another problem. After I burned the VCDs and played them on my DVD player, all of the videos seem a lil stretched out and off of the screen (the top of people's heads are a lil cut off) - the fitted the screen perfectly if burn VCDs on Nero's simple VCD program.
